Several studies have found that oil pulling daily lowers germs in the mouth and plaque and gingivitis. 

Streptococcus mutans is a kind of bacteria that causes plaque and gingivitis in the mouth. In one study, everyday swishing with sesame oil reduced Streptococcus mutans in saliva in as little as one week.

Unfortunately, no scientific research has been conducted to demonstrate that oil pulling whitens your teeth. However, it is a safe method that is worth a shot. Many people report that regular oil pulling makes their teeth whiter and brighter.

Put one tablespoon of coconut oil in your mouth and push and draw the oil between your teeth to oil pull. At room temperature, coconut oil is solid, so you may need to wait a few seconds for it to melt. Continue with the oil pulling for another 15–20 minutes.

If you spit the coconut oil into a toilet or trash can, it may solidify and produce a clog in your drain pipes.

Coconut oil pulling, unlike many other tooth whitening techniques, does not expose your teeth to acid or other elements that destroy the enamel. This means it is safe to do daily.

Brush Your Teeth With Baking Soda 

Baking soda has natural whitening effects, which is why it is commonly used in commercial toothpaste.

It’s a moderate abrasive that can aid in the removal of surface spots on teeth.

Furthermore, baking soda creates an alkaline environment in your mouth, which inhibits the growth of bacteria.

This is not a quick fix for teeth whitening, but you should see a difference in the appearance of your teeth over time.

Although science has yet to confirm that brushing your teeth with simple baking soda would whiten them, multiple studies have shown that toothpaste containing baking soda has a substantial whitening impact.

According to one study, toothpaste containing baking soda was much more successful than regular toothpaste without baking soda to remove yellow stains from teeth. The stronger the action, the higher the concentration of baking soda.
